Episcleritis periodica fugax, left eye

This code signifies a recurrent, self-limiting inflammation of the episclera, specifically affecting the left eye. It is characterized by sudden onset of redness, irritation, and sometimes pain, which typically resolves spontaneously within a few days. The condition is benign and does not involve the deeper scleral layers.

Apply this code when documentation clearly indicates a diagnosis of episcleritis periodica fugax, with explicit laterality specified as the left eye. Supporting documentation should describe the episodic nature of the inflammation and its transient resolution. This code is appropriate for initial encounters and subsequent recurrences of this specific condition.

• Ensure the documentation explicitly states "periodica fugax" or describes the recurrent, transient nature of the episcleritis to differentiate from other forms.
• Verify laterality; separate codes exist for the right eye (H15.111) and bilateral involvement (H15.113).
• Do not confuse with scleritis (H15.0-), which involves deeper inflammation and is typically more severe and prolonged.
